Q. If a scale economy is the dominant technological factor establishing or defining comparative advantage, then the underlying facts explaining why a particular country dominates world markets in some product can be pure chance, or historical accident. Explain, and compare this with the answer you could give for the Heckscher-Ohlin model of comparative advantage.
Answer: This statement is correct since the reason the seller is a monopolist may be that it happened to have been the first to produce this product in this country. It may possibly have no connection to any supply or demand related factors nor to any natural or man-made availability. This is all closely the opposite of the Heckscher-Ohlin Neo-Classical model's explanation of the determinants of comparative advantage.
